Outcomes and Morphologic Changes of Immediate Type Ia Endoleak following Endovascular Repair of Acute Type B Aortic Dissection

The majority of immediate type Ia endoleaks following TEVAR in acute type B aortic dissections could seal spontaneously, without additional procedures needed. However, the appearance of such complications could be a risk factor of poorer aortic remodeling. Careful surveillance is recommended more frequently in patients with immediate type Ia endoleaks.
